Minimal contact replaceable acoustic coupler
An acoustic coupler adapted for use with an intracanal receiver module can be deeply inserted into the ear canal of the user while making minimal contact with the walls of the ear canal. The minimal contact feature of the invention allows the acoustic coupler to seal the ear canal acoustically and anchor a hearing device at an optimal depth within the ear canal, while maximizing the user's comfort. The acoustic coupler is manufactured from a soft, pliable elastomer that allows it to conform readily to the shape of the ear canal. The acoustic coupler incorporates structural supports that allow the coupler to maintain an acoustical seal and withstand the inward pressure of the ear canal wall while making minimal contact with the ear canal. The invention incorporates a cerumen-protecting feature that prevents damage to a hearing device from infiltration of earwax into the sound port of the receiver. A vent pathway for control of occlusion effects is also provided. A user-friendly, attachment mechanism incorporating a snap-on, twist-off feature allows the acoustic coupler to concentrically surround the receiver module within the ear canal in a space-efficient manner.

Method and apparatus for minimizing spectral interference due to within and between sample variations during in-situ spectral sampling of tissue
InactiveUS6839584B2Minimum footprintMinimize contactCatheterDiagnostic recording/measuringFiberTissue sample
An apparatus and method for reproducibly interfacing a living tissue sample to the measurement probe of a spectrometer instrument in-situ minimizes spectral interference related to sampling variations. A minimal contact subject interface includes supports replaceably mounted on a base. An optical coupling means, such as a fiber optic probe, contacts the measurement site through a probe aperture in the base. During use, a subject rests an extremity on the support elements, so that the extremity is reproducibly positioned and supported in relation to the optical coupling means. The supports have a small contact area, minimizing contact with the skin at the measurement site. The interface module is adjustable to fit any subject.By reproducibly positioning and supporting the body appendage using minimal contact supports, spectral interference due to variations in placement, applied pressure, and temperature transients secondary to contact with the interface module are greatly minimized.

InactiveUS7222836B2Operating means/releasing devices for valvesCheck valvesEngineeringMinimal contact
The present invention is a poppet comprising a stem and a body, with the body having a plurality of channels extending in an longitudinal direction along the periphery of the body. The channels are gas flow conduits that react to the orientation of the poppet and force the poppet to re-align itself during operation with the centerline of the regulator chamber surrounding the poppet. The plurality of channels greatly reduces the contact between the periphery of the poppet and the regulator body. The present invention further includes a bore beginning at the non-stem end of the body and extending in the longitudinal direction within the body of the poppet. The bore can receive a spring for guiding the poppet. By positioning the spring within the poppet, the spring will have minimal contact with the regulator body. The bore avoids the spring from guiding the poppet by its end and adjusts the poppet's center of gravity toward where the poppet sits on the seat. The bore is also a part of a dead zone volume that traps debris.

Contoured Check Valve Disc and Scroll Compressor Incorporating Same
ActiveUS20100254842A1Easy to optimizeInhibition releaseRotary/oscillating piston combinations for elastic fluidsEngine of arcuate-engagement typeCheck valveMinimal contact
A check valve is provided which may be integrated into a scroll compressor that prevents static cohesion sticking forces between a valve disc member and a retainer member of the check valve housing. Such static cohesion sticking forces may be particularly generated due to oil mist generation in such scroll compressors which create a thin lubricant film between the valve disc and the stop plate of the check valve housing, creating suction type static cohesion when dislodgment of the valve disc away from the stop plate is attempted. A relief region is created between the retainer and the valve disc creating a minimal contact surface area that greatly reduces and / or eliminates such static cohesion sticking forces. For example, the valve disc may be dished to have a concave surface that faces the retainer element provided by the stop plate.
